Problems solved by technology

[0002] After decades of development and extensive promotion and application, range hoods have become one of the necessary kitchen appliances for thousands of households. Now there are many different types of range hoods produced by different manufacturers with different structures, but the main ones are The improvement of the function only revolves around the range hood itself
With the improvement of people's living standards, the requirements for range hoods are getting higher and higher. Although some existing range hoods can automatically extinguish the fire when there is a fire, they cannot identify whether there is someone on the scene, and it is easy to operate incorrectly. and contaminate the food being processed
Existing range hoods cannot prevent safety accidents, and cannot allow people to obtain information and stop losses in time

Abstract

The invention discloses a control method of a safety protection device for a domestic range hood. The control method comprises the following steps: entering an automatic detecting state when surrounding human feature information is not detected; continuously collecting and feeding back smoke concentration information, fire source information and gas component concentration around a cooking bench;comparing the smoke concentration information, the fire source information and the gas component concentration information which are collected with preset value; outputting a control signal for carrying out sprinkling, exhausting and air source turn-off treatment; transmitting related information through a wireless transmission mode. According to the control method disclosed by the invention, warning information can be provided for a user in time, and the purpose of initiative safety protection is achieved. The invention also discloses the safety protection device for the domestic range hood.By using the control method disclosed by the invention, a fire is prevented in time, potential safety hazard caused by gas leakage can be prevented, and the safety is increased.
