Embodiment Construction

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like figure 1 , figure 2 The shown high-performance range hood includes a chassis 1, a fume collecting hood 2 located at the bottom of the chassis and communicated with the chassis, and a centrifugal fan system disposed in the chassis. A control display panel 3 is installed on the front side of the fume collecting hood. , an oil collecting assembly is arranged in the fume collecting hood, an oil cup 10 is arranged at the bottom of the side of the fume collecting hood away from the control display panel, and an oil collecting plate 11 is arranged along the length of the case at the corner position of the top of the chassis close to the control display panel. The oil collecting assembly includes the oil collecting metal mesh plate 12 and the oil guide plate 13 (see image 3 ), the oil-collecting metal mesh plate is a regular hexagonal struc...

Abstract

The invention discloses a high performance extractor hood which comprises a chassis, an exhaust fume collecting hood, a control panel and a centrifugal fan system. The centrifugal fan comprises a volute, an impeller, a direct current variable frequency motor and an air guide ring. The counter line of the outer edge of the volute forms a spiral volute type line. The radial width of the inner cavityof the volute is increased progressively from inside to outside along the volute type counter line. A spiral gas runner is formed in the inner cavity. The air outlet direction of an air flow channelis arranged along the open direction of the volute type line. An air guide channel is arranged in an air outlet seat on the outer side of the air outlet of the gas runner. The air guiding direction ofthe air guide channel and the air outlet direction of the gas runner are arranged along same track and direction. The air guide channel and the gas runner jointly form a pressure-expanding channel which expands the pressure in a single direction. An oil collecting assembly is arranged in the exhaust fume collecting hood. An oil cup is arranged in the bottom of the exhaust fume collecting hood. Anoil collecting plate is arranged on the top of the chassis. The high performance extractor hood disclosed by the invention is scientific and reasonable in design, great in air quantity and air pressure, low in noise and good in oil grease separating degree, and oil drip and smoke escape are unlikely to happen.

Description

technical field [0001] The invention relates to a kitchen appliance, in particular to a high-performance range hood. Background technique [0002] With the improvement of people's lives, the requirements for the quality of life also increase accordingly. As an important part of kitchen appliances, range hoods have a great impact on people's daily life. Improving the comprehensive performance of range hoods is also a must for every range hood manufacturer. The urgent thing to do is that the existing range hoods generally have a small air volume, the smoke exhaust is not smooth in the actual use process, the air pressure is not enough, etc., and the noise is always loud, and the phenomenon of smoke running often occurs during the user's use. , especially when a large amount of oil fume rises, the oil fume is not sucked cleanly, which leads to the smell of oil fume in the whole kitchen; the oil hood often appears dripping oil after a period of use, causing a lot of cleaning tro...
