Range hood capable of adjusting lampblack suction mode according to lampblack amount

Abstract

The invention relates to the related field of range hoods, and discloses a range hood capable of adjusting a lampblack suction mode according to the lampblack amount. The range hood comprises a main box body, a lifting cavity with an upward opening is arranged in the main box body, a main screw rod upwards extending into the lifting cavity is rotatably and cooperatively connected in the lower end wall of the lifting cavity, and a lifting box body is slidably and cooperatively connected to the front and rear walls of the lifting cavity. A lifting control cavity is formed in the lifting box body, a main lead screw which extends downwards into the main box body and extends upwards into the lifting cavity is connected into the lower end wall of the lifting control cavity in a sliding fit mode, and the concentration of the lampblack is detected through rays, so that the range hood is automatically in two modes, and when the lampblack is less, the range hood uses a silent gear. By means of side suction, cooking and other operations can be facilitated while lampblack is effectively exhausted, head collision is avoided, noise is low, when lampblack is more, a powerful gear is switched, effective lampblack exhaust is achieved by increasing the motor power and the orientation of a suction opening of the range hood, meanwhile, the range hood is hidden through lifting of the range hood, and the occupied area of the range hood when the range hood is not used is reduced.

Description

technical field [0001] The invention relates to the related field of range hoods, in particular to a range hood which adjusts a smoking mode according to the amount of fumes. Background technique [0002] The range hood is a home kitchen appliance for absorbing cooking fumes and other electrical appliances. It is mostly used in Chinese-style range hoods and side-suction range hoods. The biggest problem with Chinese-style range hoods is that they take up space, are noisy, and are easy to bump into each other. The range hood is not easy to touch, and the appearance is stylish. When there is less oil fume, it is easier to smoke because the smoking port is close to the point where the oil fume occurs. Therefore, when the motor power is low, it can also produce good smoking effect and low noise. Effective smoking. Contents of the invention [0003] The object of the present invention is to provide a range hood that adjusts the smoking mode according to the amount of soot, whic...
