Background technique

A range hood, also known as a range hood, is a kitchen appliance that purifies the kitchen environment. With the improvement of people's living standards, range hoods have become an indispensable kitchen equipment for modern families.

At present, the common range hoods are mainly divided into three categories: one is the Chinese range hood, the other is the European range hood, and the third is the side suction range hood. The biggest problem of Chinese-style range hoods is that they take up space, are noisy, easy to touch, drip oil, the oil fume is not clean, and it is inconvenient to clean; while the power of European-style range hoods is generally above 300 watts, which consumes electricity and is expensive. Net cleaning is also inconvenient. The side-suction range hood has an exhaust fume effect of more than 99%, does not drip oil and does not touch the head. It is hidden in the cabinet and integrated with the cabinet, and does not take up space. It is gradually favored by the majority of users.

Existing side suction range hoods generally have a volute in the box, a motor-driven wind wheel in the volute, an air outlet on the upper part of the wind wheel, an air inlet in front of the wind wheel, and a single air inlet in the air inlet. There is a long slit oil filter inner net, and a rectifying plate is arranged in front of the oil filter inner net. In the actual cooking process, when the oil fume passes through the long strip holes of the single-layer oil filter inner net, a large amount of vortex airflow will be generated behind the hole, causing the oil fume to collide with the oil filter net, so that the oil fume is separated and filtered out. The effect of soot. After adding the oil filter inner net, the oil filtering effect of the whole range hood is very good, but because the area of the air inlet is reduced, the air volume is reduced, and a large amount of vortex air flow will be generated behind the long holes, which greatly increases the range hood. noise.
