Intelligent fireproof control method, fireproof auxiliary control system and fireproof control system

Abstract

The invention relates to an intelligent fireproof control method, a fireproof auxiliary control system and a fireproof control system, and the method comprises the steps: detecting a flame height value of a kitchen range when judging that a detected vertical movement distance value of a cooking utensil moving upwards relative to the kitchen range is greater than or equal to a preset movement distance threshold value; once it is judged that the detected flame height value exceeds the preset flame height threshold value, the flame height of the cooker is adjusted to be smaller than the preset flame height threshold value, and when it is detected that the oil mist concentration value below the range hood exceeds the preset oil mist concentration threshold value, mist-shaped oil mist diluent is controlled to be sprayed to the position below the range hood; therefore, the oil mist with the current concentration is diluted into the oil mist with the lower concentration. Thus, the situation that flames exceeding the normal height point oil stains accumulated on the range hood is avoided, the fireproof effect is achieved, and it can be guaranteed that a user can continue to use the flames in the burning state to conduct cooking operation under the condition that it is guaranteed that the oil mist diluent does not extinguish the normal flames.

Description

technical field [0001] The invention relates to the field of kitchen electrical equipment, in particular to an intelligent fire prevention control method, a range hood and an intelligent fire prevention control system. Background technique [0002] In the field of kitchen appliances, range hoods and stoves are two important pieces of equipment. After the cooker is started, the activated range hood can extract the oil fume generated by the cooking equipment and discharge it to the outside, so as to keep the air in the kitchen clean. [0003] After long-term use of the range hood, the surface of the range hood will be covered with oil stains. With the increase of use time, the oil droplets generated by these oil stains will drip and accumulate on the cooker, causing the oil droplets accumulated on the cooker to be heated under high temperature. Create a fire safety hazard. [0004] Chinese invention patent application CN110107941A discloses a commercial oil fume purification...

AI Technical Summary

Problems solved by technology

[0005] However, the above-mentioned invention patent application CN110107941A also has some problems: along with the continuous accumulation of oil stains on the range hood, once the flame height produced by the cooker reaches a certain height during the cooking process, the flame is very easy to ignite the range hood. Accumulated oil pollution, causing fire

Obviously, the fire extinguishing control scheme in this invention patent application CN110107941A is difficult to produce timely prevention and control of fire hazards caused by the flame of the cooker, and it is impossible to prevent fire prevention while ensuring that the flame is at a normal height.
