Embodiment

[0016] Embodiment: A non-oil accumulating air guide structure of a range hood, including a bellows 2 and an impeller, the impeller is located inside the bellows, and an air guide ring 1, and the air guide ring is installed in the air inlet channel An inclined air guiding surface 11 is formed on the inner wall of the air guiding ring, and the inclined direction of the air guiding surface points to the inner side of the impeller. After the airflow enters the air guide ring, it is guided by the inclined air guide surface, so that the air flow enters the fan impeller regularly, avoiding the occurrence of turbulent flow areas caused by irregular air flow, and thus making the range hood enter the air smoothly. Ensure the normal flow of air flow. The airflow inhaled by the range hood is guided by the air guide surface of the air guide ring and directly enters the inner side of the impeller, which increases the air volume of the range hood and reduces the noise. The air guiding surfa...

Abstract

The invention discloses an oil-accumulation-free air guiding structure of a range hood. The oil-accumulation-free air guiding structure comprises a wind bellow, multiple blades and an air guiding ring, wherein the blades are arranged in the wind bellow, the air guiding ring is installed in an air inlet channel; an inclined air guiding plane is formed in the inner side wall of the air guiding ring and the inclined direction of the air guiding plane points to the inner sides of the blades; and an oil discharging port is formed in the air guiding ring, so that the accumulated oil at the bottom of the wind bellow can be discharged.

Description

technical field [0001] The invention relates to an air guide structure, in particular to an air guide structure without oil accumulation of a range hood. Background technique [0002] At present, when the range hood is working, the inhaled airflow flows from both sides of the impeller to the inside of the impeller, and through the rotation of the impeller, the airflow is pushed out of the impeller by the blades. During this process, the air flow in the axial direction is not guided, and a strong turbulent flow area is formed at the bottom edge of the impeller, which makes the air flow unable to circulate normally, thereby affecting the ventilation volume of the fan and generating greater noise. Moreover, due to long-term use, oil stains will accumulate at the bottom of the bellows and cannot be eliminated. Contents of the invention [0003] The problem solved by the invention is to overcome the above-mentioned existing deficiencies, break through the limitations of the ex...
