Kitchen ventilator

Abstract

The invention discloses a kitchen ventilator which comprises a kitchen ventilator body and a lampblack rotating collecting device. The kitchen ventilator body is provided with a lampblack suction inlet and a lampblack exhaust port. The lampblack rotating collecting device comprises an air guide plate, an air flue is arranged in the air guide plate, and an air inlet and an air outlet communicating with the air flue are formed in the air guide plate. The air guide plate forms tornado-shaped cyclone through airflow sprayed out of the air outlet. According to the kitchen ventilator, forceful shearing force is achieved on surrounding air and lampblack, and therefore the surrounding air and the lampblack are driven to flow; and finally the tornado-shaped cyclone is formed, it is guaranteed that the lampblack spirally rises under the strong suction force action of the cyclone, the lampblack can be prevented from spreading all around, and the suction force range of the kitchen ventilator is widened. Therefore, the power needs of the kitchen ventilator are reduced, energy consumption is reduced, then the work noise of the kitchen ventilator is lowered, and the quality of the kitchen ventilator is improved.

Description

technical field [0001] The present invention relates to the technical field of kitchen appliances, more specifically, to a range hood. Background technique [0002] The range hood generally generates a certain negative pressure at the smoke outlet through the rotating impeller, and then attracts the nearby airflow to flow in. However, in fact, this attraction decreases rapidly as it moves away from the smoke outlet. Under the standard installation height of the range hood, The suction force of the range hood has reached the surface of the stove very weakly, so the oil fume cannot get enough power to move to the smoke outlet. Furthermore, the direction of the suction force generated by the range hood is divergent, and the range hood draws a lot of air from other directions, not just the oil fume from below, resulting in a small amount of oil fume per unit time. But if the cooking fume cannot be sucked away in time, it will be affected by gravity and spread to all directions,...

Problems solved by technology

[0002] The range hood generally generates a certain negative pressure at the smoke outlet through the rotating impeller, and then attracts the nearby airflow to flow in. However, in fact, this attraction decreases rapidly as it moves away from the smoke outlet. Under the standard installation height of the range hood, The suction force of the range hood reaches the surface of the cooktop is already very weak, so the oil fume cannot get enough power to move to the smoke outlet

Furthermore, the direction of the suction force generated by the range hood is divergent, and the range hood draws a lot of air from other directions, not just the oil fume from below, resulting in a small amount of oil fume per unit time. But if the cooking fume cannot be taken away in time, it will be affected by gravity and spread to all directions, and cannot be taken away by the range hood.

Therefore, the range hood of the related art has a limited suction range, and the suction range cannot be increased, and the range hood cannot be effectively improved, and the energy consumption is large and the noise is large.
