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.

Embodiment 1

[0043] The first embodiment provides an intelligent fire prevention control method. Specifically, see figure 1 As shown, the intelligent fire control method of this embodiment includes the following steps:

[0044] Step 1: Detect the vertical movement distance value of the cooking utensil moving up relative to the stove; wherein, it is assumed that the detected vertical moving distance value of the cooking utensil moving up relative to the stove in this embodiment is marked as D, and the cooking utensil is a frying pan;

[0045] Step 2, according to the detected vertical movement distance value to make judgment processing:

[0046] When the vertical movement distance value is greater than or equal to the preset movement distance threshold D 0 when D≥D 0 , it means that the frying pan as a cooking utensil is turned or lifted by the user at this time, which may cause the flame height of the cooker to move up, then go to step 3; If there is no situation that causes the flame ...

Embodiment 2

[0060] The second embodiment also provides an intelligent fire prevention auxiliary control system that cooperates to implement the above-mentioned intelligent fire prevention control method. Specifically, see figure 2 As shown, the intelligent fire prevention auxiliary control system of this embodiment includes an oil fume sensor 11, an injection device 12, a first detection device 13, a second detection device 14 and a controller 15. The controller 15 is respectively connected to the oil fume sensor 11, the injection device 12, the first detection device 13, the second detection device 14, and the controller 15. The first detection device 13 and the second detection device 14; wherein:

[0061] The oil fume sensor 11 is responsible for detecting the oil mist concentration value under the operating range hood. The "below the range hood" referred to here specifically refers to the space between the fume collecting hood 10 of the range hood 1 and the cooker 2;

[0062] The sp...

Embodiment 3

[0068] The third embodiment also provides an intelligent fire prevention control system including the cooker 2 . see Figure 5 As shown, the difference from the second embodiment is that in the third embodiment, at least one of the oil smoke sensor 11, the first detection device 13, the second detection device 14 and the controller 15 in the intelligent fire prevention auxiliary control system is set on cooktop 2. For example, the first detection device 13 and the second detection device 14 may be arranged on the cooktop 2 as required.

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...
