Problems solved by technology

However, at present, the public flues of high-rise residential buildings in China are narrow and have high resistance, and devices such as check valves are installed at the rear end of the range hood. When the air volume is less than the air volume when the range hood is running alone, the advantages will be greatly reduced

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] like Figure 1-11 As shown, a range hood includes a fume collecting hood 1 located below and a bellows 3 located above the fume collecting hood 1. An air inlet 11 is opened on the fume collecting hood 1. The bellows 3 includes a casing 30 and is arranged on the The fan system 4 in the casing 30, so that the oil fume can enter the air box 3 through the air inlet 11, and then be discharged into the public flue through the air outlet cover 8 on the top of the air box 3. The shell 30 has a square appearance and is composed of a shell body 301 and a front cover 302 , a left cover 304 , a right cover 303 , and a rear cover 305 covered on the shell body 301 . That is, the housing body 301 has openings on the front side, the left side and the right side, and the front side cover 302, the left side cover 304, and the right side cover 303 are re...

Abstract

The invention relates to a high-performance range hood. The high-performance range hood comprises a smoke collecting cover with an air inlet, the smoke collecting cover is internally provided with a rectification plate located below the air inlet, an air box is arranged above the smoke collecting cover, and the air box comprises a shell and a fan system arranged in the shell. The high-performancerange hood is characterized in that an auxiliary air inlet is formed in the side wall of the lower part of the shell and can communicate with an air inlet port of the fan system, and in a working state, the auxiliary air inlet is at least opposite to a vortex formed by airflow outside the shell. Main airflow and auxiliary airflow are formed outside the range hood, and forming of the gas vortex isavoided. Inlet air of the fan system is supplemented through the auxiliary air inlet, lampblack floating to the upper part of the smoke collecting cover is captured again, thus the lampblack suction effect of the range hood is improved, the situation that the lampblack is accumulated on the outer surface of the shell is avoided, and the range hood is conveniently cleaned and maintained daily.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a high-performance range hood. Background technique [0002] The island type range hood is a range hood that is installed on the ceiling of an open kitchen or other open places and is suspended around. At present, although open kitchens and island range hoods have entered China for many years, many consumers are hesitant to open kitchens. concern. It can be seen that the improvement of the performance of the island type range hood is the key to the promotion of it and the open kitchen in China. [0003] At present, the following methods are mainly used to improve the range hood's range hood performance: (1) Enlarging the area of ​​the smoke collection hood: During the process of rising, the range hood gradually diffuses to the surroundings by free diffusion, increasing The area of ​​the fume collection hood can increase the negative pressure area, so that the continuously diffused o...
