An automatic lifting range hood

Abstract

The invention discloses a novel automatic rising-falling extractor hood which comprises a machine shell, a wind chamber, a motor box, a threaded soft pipe, a fixing box, a fixing rod, a rack, a driving box and a rotating motor. The machine shell is internally provided with the wind chamber and the motor box from left to right, the upper end of the wind chamber communicates with a smoke vent, the smoke vent vertically and upwards extends to penetrate the upper end of the machine shell to communicate with the threaded soft pipe, the fixing box is arranged on the right side of the machine shell,the fixing rod is arranged on the right side of the fixing box, the rack is arranged on the right side of the fixing rod, the driving box is arranged on the right portion of the rack, a driving gear,a fixed gear and a driven gear which are meshed with each other are arranged in the driving box, and the left portion of the driven gear penetrates the driving box to be meshed with the rack. The novel automatic rising-falling extractor hood is obvious in lampblack sucking effect, rising and falling of the extractor hood are continuously adjusted according to the actual condition, when the lampblack amount is too large, the lampblack is blocked, sucked and removed in time through automatic rising and falling, the lampblack gathering effect is effectively improved, meanwhile, the user experience effect is improved, and the wide market prospect is achieved.

Description

technical field [0001] The invention relates to the field of kitchen utensils, in particular to an automatic lifting range hood. Background technique [0002] Early home kitchen smoke exhaust work was done by exhaust fans. Although the exhaust fan can remove most of the oily fumes in the kitchen, it is unable to solve the pollution of the whole kitchen caused by the oily fumes during cooking. The oily fumes produced during cooking contain many substances harmful to the human body. Work can cause many diseases. Nowadays, with the rapid development of science and technology in China, every family kitchen will be equipped with a range hood. The range hood is also called a range hood. It is a common kitchen appliance that purifies the kitchen environment. , can quickly take away the waste burned by the stove and the oil fume harmful to the human body produced during the cooking process, and discharge it outside, reduce pollution, purify the air, and have the function of anti-v...

Problems solved by technology

[0003] Since the fume will have three stages of explosion, rising and spreading, the best way to smoke the fume is to suck the fume in before the fume diffuses. However, the installation of the range hood is too low to block the user's cooking sight, it is easy to bump into each other, and it also hinders the use of special cookware. Therefore, it is necessary to continuously adjust the height of the range hood according to the actual situation in order to effectively improve the effect of the range hood

However, conventional range hoods are fixedly installed above the kitchen stove and cannot be lifted up and down. Therefore, an automatic lifting range hood is designed, which can make the user experience better and the effect of collecting smoke better, which has become an urgent problem to be solved
