An adjustable air curtain, its control method and a range hood

Abstract

The invention relates to an adjustable air curtain, a control method and a range hood. The real-time exhaust air volume is monitored by a sensor installed in the exhaust pipe or by monitoring the motor parameters of the range hood, and at the same time the signal is transmitted to the air curtain for control. According to the relationship between the input exhaust air volume and the outflow parameters of the air curtain, adjust the speed of the air curtain fan and the direction of the guide vanes to change the outflow parameters of the air curtain, that is, the outflow speed and angle of the air curtain. Therefore, under the condition that the exhaust air volume of the range hood changes, correspondingly changing the outflow parameters of the air curtain can achieve the purpose of better realizing the effect of the air curtain.

Description

technical field [0001] The invention relates to the field of intelligent control, in particular to an adjustable air curtain, 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 fumes 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 quality 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 form of the suction port of the range hood, adding side panels, and so on. Air curtain range hoods are also a way to improve capture performance. In the design process of air curtain type range hoods in the past, the design method of fixed parameters is often adopted, that is, the same air curtain outflow parameters are used for different exh...

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.
