Adjustable air curtain, control method and range hood

Abstract

The invention relates to an adjustable air curtain, a control method and a range hood. The real-time exhaust air rate is monitored through a sensor installed in an exhaust pipe or by monitoring parameters of a motor of the range hood, meanwhile, a signal is transmitted to an air curtain controller, and according to the relation between the input exhaust air rate and air curtain outflow parameters,the outflow parameters of the air curtain, namely the outflow speed and angle of the air curtain, are changed by adjusting the rotating speed of an air curtain fan and the direction of guide vanes. Under the condition that the exhaust air rate of the range hood is changed, the air curtain outflow parameters are correspondingly changed, and the purpose of better achieving the air curtain effect can be achieved.

Description

Technical field [0001] The invention relates to the field of intelligent control, in particular to an adjustable air curtain and a control method and a range hood. Background technique [0002] The range hood is an important local exhaust equipment in the kitchen, which plays a role in removing cooking fume in the kitchen and creating a healthy and comfortable indoor living environment. Among them, the collection performance of the range hood is an important index to evaluate the pros and cons of the range hood. There are many ways to improve the collection performance, such as increasing the exhaust air volume of the range hood, changing the suction port of the range hood, adding side panels, and so on. Air curtain type range hoods are also a way to improve collection performance. In the past design process of air-curtain range hoods, a fixed parameter design method is often used, that is, the same air curtain outflow parameters are used for different range hoods. Research an...

AI Technical Summary

Problems solved by technology

Research and practice have proved that the air curtain parameters designed for a certain exhaust air volume will be ineffective or even have the opposite effect when used for other exhaust air volumes, and the air curtain cannot play its due role, which is not conducive to the kitchen Cooking Fume Control

At the same time, in practical applications, due to the impact of residential flue pressure fluctuations, the exhaust air volume of range hoods often deviates from the rated value under the corresponding gear, and the fixed-parameter air curtain cannot adapt to the complex kitchen environment in the cooking process.
