Problems solved by technology

[0006] For the above-mentioned range hood, the fan system is placed on the top, and the air inlet is arc-shaped, so that the suction port of the fan system and the air inlet of the fume collecting hood are not on the same plane. Flow loss, increased waste work of the fan system
Moreover, after the fan system is placed on the top, the overall space occupied by the range hood is increased.

Abstract

The range hood comprises a hollow box body and fan systems, the box body comprises a left side plate and a right side plate, a first air inlet is formed in the left side plate, a second air inlet is formed in the right side plate, the fan systems are arranged in the box body, and the two fan systems are arranged on the left side and the right side to form parallel double fans; each fan system is provided with a fan air inlet, the fan air inlet of the fan system located on the left side is right opposite to the first air inlet, and the fan air inlet of the fan system located on the right side is right opposite to the second air inlet. Compared with the prior art, the range hood has the advantages that the fan system is arranged at the lower part and is opposite to the air inlet of the box body, so that direct suction is realized, the space of an upper fan frame is saved, the whole oil smoke flowing path is simple, and idle work of a power system does not need to be increased due to flowing loss caused by a lengthy air duct; meanwhile, the structure is compact, the space of an upper cabinet can be saved, and the cooking operation experience of a user is not affected while the oil smoke suction effect is ensured.

Description

technical field [0001] The invention relates to a lampblack purification device, in particular to a lampblack machine. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern homes. The range hood uses the principle of fluid dynamics to work. The centrifugal fan installed inside the range hood sucks and discharges the oil fume, and uses the filter screen to filter some grease particles. The centrifugal fan includes a volute, an impeller installed in the volute, and a motor that drives the impeller to rotate. When the impeller rotates, a negative pressure suction is generated in the center of the fan, and the oil fume under the range hood is sucked into the fan. After being accelerated by the fan, it is collected by the volute and guided out of the room. [0003] Range hoods are usually divided into top suction, side suction and low suction. The top suction range hood adopts the principle of oil fume ascending, which gene...
