s11: and acquiring a first temperature of flame when the stove is burnt.
The controller of the stove acquires a first temperature of flame when the stove is burning, wherein the first temperature refers to the current temperature when the stove is burning. Specifically, the controller may obtain a first temperature of the flame via the thermocouple.
Specifically, the controller can obtain the first temperature of the flame when the stove is burning after receiving an obtaining instruction of a user. For example, when a user wants to adjust the fire of the cooker, an acquisition instruction is input into the cooker, and the cooker receives the acquisition instruction and starts to acquire the first temperature of flame when the cooker is burning.
In other embodiments, the controller may obtain the first temperature of the flame at predetermined intervals, where the predetermined intervals may be 30 seconds, 1 minute, 5 minutes, or 10 minutes, and may be adjusted according to actual use requirements. For example, the controller may acquire the first temperature of the flame once every 5 minutes, i.e., the controller may perform the fire adjustment once every 5 minutes.
S12: and responding to the first temperature being lower than the preset temperature value, adjusting the air inlet speed of the air inlet component within a first preset range and/or adjusting the opening degree of the gas regulating valve within a second preset range.
After the controller acquires the first temperature of the flame, whether the first temperature is higher than a preset temperature value or not is judged, when the controller confirms that the first temperature is lower than the preset temperature value, the gas can be considered to be not fully combusted, and at the moment, the air inlet speed of the air inlet assembly is adjusted within a first preset range and/or the gas adjusting valve is adjusted within a second preset range.
Wherein, the preset temperature value can be the temperature value when the gas is fully combusted. Optionally, the gas inlet amount is made to reach an air coefficient of 1.03-1.06 for better mixing with air, and the flame temperature value of the stove is set as a preset temperature value under the air coefficient. For example, the preset temperature value may be 1000 degrees, 1200 degrees, 1300 degrees, or the like.
In one embodiment, when the controller determines that the first temperature is lower than the preset temperature value, the air intake speed of the air intake assembly can be adjusted only within a first preset range. The first preset range may be: 50% -150% of the air inlet speed of the current air inlet component is used for fine adjustment of the air inlet component. The air inlet speed of the current air inlet component refers to the air inlet speed corresponding to the current gear of the air inlet component. Specifically, when the air inlet component is adjusted, the air inlet speed can be increased from 50% of the current air inlet speed in sequence until the air inlet speed reaches 150% of the current air inlet speed; the air inlet speed can also be reduced from 150 percent of the current air inlet speed in sequence until the air inlet speed is reduced to 50 percent of the current air inlet speed. In other embodiments, the wind speed may be gradually increased from the current wind inlet speed of the air inlet assembly until the wind speed reaches 150% of the current wind inlet speed, and then the wind speed is returned to the current wind inlet speed, and then the wind speed is gradually decreased until the wind speed is decreased to 50% of the current wind inlet speed.
In another embodiment, the first predetermined range may also be from a maximum air intake speed to a minimum air intake speed corresponding to the air intake assembly, which may make the air intake speed adjustable in a wider range. In other embodiments, the first preset range may also be another range, such as 70% -130% or 80% -120% of the air intake speed of the current air intake assembly, and may be specifically selected according to the actual use situation, which is not listed here.
In another embodiment, when the controller determines that the first temperature is less than the preset temperature value, the gas regulating valve may be adjusted only within a second preset range. The second preset range can be 80% -120% of the opening degree corresponding to the current gas regulating valve, so that the gas regulating valve can be finely adjusted. The opening degree corresponding to the current gas regulating valve refers to the opening degree corresponding to the current gear of the gas regulating valve. Specifically, when the gas regulating valve is regulated, the opening degree can be sequentially increased from 80% of the opening degree corresponding to the current gas regulating valve until the opening degree corresponding to the gas regulating valve reaches 120% of the opening degree of the current gas regulating valve; or the opening degrees of the gas regulating valves can be reduced from 120% of the current opening degree of the gas regulating valves in sequence until the opening degree corresponding to the gas regulating valves is reduced to 80% of the current opening degree of the gas regulating valves. In other embodiments, the opening degree may be gradually increased from the opening degree corresponding to the current gas regulating valve until the opening degree of the gas regulating valve reaches 120% of the opening degree corresponding to the current gas regulating valve, and then the current opening degree of the gas valve is returned, and then the opening degree is gradually decreased until the opening degree of the gas valve is decreased to 80% of the opening degree corresponding to the current gas valve.
In another embodiment, the second preset range may be between a minimum opening degree and a maximum opening degree of the gas regulating valve, so that the gas regulating valve is adjusted within the maximum range. In other embodiments, the first preset range may also be other ranges, such as 90% -110% or 70% -130% of the opening degree corresponding to the current gas regulating valve, and may be specifically selected according to actual use conditions, which are not listed here.
In yet another embodiment, both the air intake assembly and the gas regulator valve may be adjusted when the controller determines that the first temperature is less than a predetermined temperature value. For example, in one embodiment, the air intake assembly may be adjusted within a first predetermined range, and then the gas regulator valve may be adjusted within a second predetermined range. In another embodiment, the gas regulating valve can be adjusted within a second preset range, and then the air intake assembly can be adjusted within the first preset range.

Specifically, in the process of adjusting the air inlet assembly and/or the gas adjusting valve, the second temperature of the flame is acquired in sequence. In a specific embodiment, the second temperature of the flame is obtained in real time during the adjustment of the air intake assembly and/or the gas regulating valve. In another embodiment, the second temperature may be obtained at regular intervals during the adjustment of the air intake assembly and/or the gas regulating valve, such as every 2S, 5S or 60S. In other embodiments, when the air intake assembly is adjusted, when the air intake speed of the air intake assembly increases or decreases by a preset speed value, the second temperature of the primary flame is obtained to obtain a plurality of second temperatures. For example, when the air intake speed of the air intake assembly is increased or decreased by 10%, the second temperature is obtained once. In the process of adjusting the gas regulating valve, when the opening degree of the gas regulating valve is increased or decreased by a preset value, the second temperature of the primary flame is obtained to obtain a plurality of second temperatures again. For example, when the opening degree of the gas regulating valve is increased or decreased by 5%, the second temperature is acquired once, and in this way, the temperature acquisition process can be simplified.

By the mode, the cooker can have high energy efficiency.
In a specific embodiment, when the air intake assembly is adjusted, a plurality of second temperatures are sequentially obtained in the adjusting process, when the plurality of second temperatures are all smaller than the preset temperature, the largest second temperature in the plurality of second temperatures is found out, and then the air intake assembly is adjusted to the air intake speed state corresponding to the largest second temperature, so that the energy efficiency of the stove is improved.
