Automatic telescopic type extractor hood of multi-cavity structure

Abstract

The invention discloses an automatic telescopic type extractor hood of a multi-cavity structure. The extractor hood comprises air guide pipes, a draught fan assembly used for ventilation of the air guide pipes and exhaust fume collecting hood assemblies communicating with air inlets of the air guide pipes; the air guide pipes and the exhaust fume collecting hood assemblies are arranged in a grouped manner, at least two groups are arranged, the air guide pipes and exhaust fume collecting hoods are connected and positioned through telescopic assemblies, and each telescopic assembly comprises a corrugated pipe enabling the corresponding exhaust fume collecting hood assembly and the inlet of the corresponding air guide pipe to be in seal abut joint, a telescopic pipe assembly capable of driving the exhaust fume collecting hood assembly and the corrugated pipe to synchronously stretch out and draw back, and a drive mechanism capable of driving the telescopic assembly to stretch out and draw back; the multi-cavity structure and the telescopic structure are combined, multiple kinds of automation adjustment can be achieved, various smoke exhausting occasion needs can be met, the number of the running exhaust fume collecting hood assemblies can be controlled, the telescopic height of the exhaust fume collecting hood assemblies can be controlled, and the intelligent degree is higher.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to an automatic retractable range hood with a multi-cavity structure. Background technique [0002] Range hood, also known as range hood, is a kitchen appliance that purifies the kitchen environment. It is installed above the stove and can quickly suck out the exhaust gas from the stove and the oil fume generated during the cooking process and discharge it to the outside, reducing pollution and purifying the air. . [0003] Existing range hoods mainly include a smoke collecting hood (assembly), an air duct (including an air guide pipe, etc.), a motor and a wind wheel arranged in the air duct, wherein the air inlet is located in the smoke collecting hood and its orifice faces Stoves are usually equipped with a net cover on the air intake hole. When the range hood is working, the wind wheel rotates at high speed to form a negative pressure area in a certain space above the range hood, and ...

AI Technical Summary

Problems solved by technology

[0004] The air inlet of the current range hood is generally fixed relative to the stove, resulting in unsatisfactory smoking effect

Especially for occasions where the smoke is relatively heavy, it is impossible to completely suck the oil fume away, resulting in the concentration of oil fume in the kitchen air is too high, and the environment deteriorates
