Air vortex type range hood

Abstract

The invention relates to the field of kitchen smoke ventilator. Aiming at defects of low absorption rate and trouble of oil-filter screen unpicking and washing, the invention discloses an air vortex type range hood The invention is characterized by providing two different suction types: an air vortex type and an adjustable type. And two types of machines, both without an oil-filter screen, have general main members of a power portion and a general electrical principle. An air vortex generator of the air vortex type range hood can generate negative pressure suction effect like natural tornado, and maintain the advantages of a European style smoke ventilator. The adjustable type range hood is set against a wall with a fore rake of 20 DEG, and a large plane circumferential suction inlet can be adjusted freely to a state of near suction or even cover suction. The range hood has a high absorption rate, and a traditional so-called oil screen is replaced by a de-oiling technology to realize zero oil-filter screen and zero unpicking and washing, so as to change household heavy pollution area into a healthy and environmental-friendly place, and to facilitate daily cleaning. In addition, the range hood, which has a similar structure and implementation difficulty to a traditional product, is novel and unique and focuses on real effects. Therefore, the range hood has a substantial popularization value.

Description

Technical field: [0001] The invention relates to the field of kitchen and bathroom appliances, in particular to a kitchen range hood. Background technique: [0002] There are many well-known brands of traditional range hoods, but they can basically be divided into two types, one is called European style, and the other is called deep cover type. The former is indeed European style, while the latter is only different in appearance. Basically the same, the motor is placed in the middle of the impeller, mostly with double suction ports, and placed at the end of the impeller is a single suction port, with a flue discharge on the top, an oil filter on the bottom, and accessories to form a whole, especially: all brands today, especially European-style. 100% of the motors and fans are placed at the lower position of the machine, about 700mm away from the smoke source stove table, and most of the volute suction ports are located at the static pressure position, and the lower part is ...

Problems solved by technology

It is called "oil filter net", how does it "filter" oil? To "filter", the smaller and denser the holes, the better, but if the holes are too small, the suction resistance of the fan will be increased, and the small holes will be blocked by oil soon. If the holes are big, can they still be filtered? ? Besides, the oil fumes are not particles, so the main function of the "oil filter" is the oil collecting pan, otherwise, where will the oil droplets coming down from the suction port go? This brings users endless troubles in dismantling and washing
