Variable-frequency intelligent range hood with adjustable exhaust fume collecting hood

Abstract

The variable-frequency intelligent extractor hood comprises a shell, the middle of the inner top wall of the shell is fixedly connected with an oil fume suction device body, the position of an oil fume inlet in the lower surface of the oil fume suction device body is fixedly connected with a telescopic pipe, and the lower end of the telescopic pipe is fixedly connected with an oil fume collecting hood body; servo motors are fixedly connected to the left side and the right side of the inner top wall of the shell through cases correspondingly, output shafts of the two servo motors are in transmission connection with threaded rods through couplings correspondingly, the outer surfaces of the two threaded rods are in threaded connection with lifting rods correspondingly, and the servo motors work to drive the threaded rods to rotate. The lifting rod can be driven to move by matching the threads with the limiting block, so that the smoke collecting hood main body and the lower end of the telescopic pipe can be driven to descend, the distance between the smoke collecting hood main body and a cooking bench is shortened, the smoke collecting effect of the smoke collecting hood main body can be improved, and the smoke sucking device main body can conveniently suck smoke generated by cooking.

Description

technical field [0001] The invention belongs to the technical field of range hoods, in particular to an adjustable frequency conversion intelligent range hood with a smoke collecting hood. Background technique [0002] The range hood is an electrical appliance used in the home kitchen to absorb the oily fume generated during cooking. It can not only fulfill the functional role well, but also should have a decoration concept that integrates the modern kitchen pattern. After the development of the range hood, the range hood is no longer It is limited to a simple tool for removing oil fume in the kitchen, but more entertainment functions and use functions are added, such as an entertainment range hood with a TV monitor, a range hood with a security system integrated with a smart home, and a network control system. network range hood, etc. [0003] At present, when the frequency conversion intelligent range hoods on the market are in use, the distance between the smoke collecti...

AI Technical Summary

Problems solved by technology

[0003] At present, when the frequency conversion intelligent range hoods on the market are in use, the distance between the smoke collection hood and the stove is fixed. When cooking, there will be more oil fumes, and the suction of the range hood is weak and it is difficult to effectively absorb the oil fumes. As a result, the smoke collection effect of the fume collection hood on the oil fume is reduced, and the use effect of the range hood is reduced. Therefore, we propose an adjustable frequency conversion intelligent range hood with a fume collection hood
