The kitchen range is an indispensable household appliance in a kitchen, and the energy efficiency of the kitchen range is a comprehensive index for measuring the fire power and energy-saving effect of the kitchen range. In order to improve the energy efficiency of a stove, the problems of insufficient combustion, unstable firepower, large flame temperature deviation and flame regulation lag caused by different components, different pressures and different air of fuel gas are solved.
Referring to fig. 1, fig. 1 is a schematic flow chart of an embodiment of a fire control method of a stove provided in the present application, where the stove includes an air intake assembly and a gas regulating valve, the air intake assembly is used for regulating an intake air speed of air, and the gas regulating valve is used for regulating a flow rate of gas, and specifically, the control method includes:
s11: a first temperature of a flame is obtained when the cooktop is burning.
The controller of the cooktop obtains a first temperature of the flame when the cooktop burns, wherein the first temperature refers to the current temperature when the cooktop burns. Specifically, the controller may obtain the first temperature of the flame through a thermocouple.
Specifically, the controller may acquire the first temperature of the flame when the cooktop burns after receiving the acquisition instruction of the user. For example, when the user wants to perform fire adjustment on the stove, an acquisition instruction is input to the stove, the stove receives the acquisition instruction, and then the first temperature of the flame when the stove burns starts to be acquired.
In other embodiments, the controller may acquire the first temperature of the primary flame at intervals of a predetermined time, and the predetermined time may be 30 seconds, 1 minute, 5 minutes, 10 minutes, or the like, which may be specifically adjusted according to actual use requirements. For example, the controller may take a first temperature of the primary flame at 5 minutes intervals, i.e., the controller makes a fire adjustment at 5 minutes intervals.
S12: and responding to the fact that the first temperature is smaller than a preset temperature value, adjusting the air inlet speed of the air inlet assembly in a first preset range and/or adjusting the opening degree of the gas adjusting valve in a second preset range.
When the controller confirms that the first temperature is smaller than the preset temperature value, the gas is considered to be insufficiently 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.
The preset temperature value may be a temperature value when the fuel gas is fully combusted. Optionally, the air input of the gas is made to reach the air coefficient of better mixing with air to be 1.03-1.06, and the flame temperature value of the kitchen range is set to be 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 confirms that the first temperature is less than the preset temperature value, the air intake speed of the air intake assembly may be adjusted only within the first preset range. The first preset range may be: 50% -150% of the current air inlet speed of the air inlet assembly so as to finely adjust the air inlet assembly. The air inlet speed of the current air inlet assembly refers to the air inlet speed of the air inlet assembly corresponding to the current gear. Specifically, when the air inlet assembly is regulated, 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 be sequentially reduced from 150% of the current air inlet speed until the air inlet speed is reduced to 50% of the current air inlet speed. In other embodiments, the air speed of the current air intake assembly may be gradually increased from the air intake speed until the air intake speed reaches 150% of the current air intake speed, then the current air intake speed is returned, and then the air intake speed is gradually reduced until the air intake speed is reduced to 50% of the current air intake speed.
In another embodiment, the first preset range may be between the maximum air intake speed and the minimum air intake speed corresponding to the air intake assembly, so that the air intake speed can be adjusted in a wider range. In other embodiments, the first preset range may be other ranges, for example, 70% -130% or 80% -120% of the current air intake speed of the air intake assembly, and may specifically be selected according to actual use conditions, which is not specifically described herein.
In another embodiment, the gas regulating valve may be adjusted only in a second preset range when the controller confirms that the first temperature is less than the preset temperature value. The second preset range can be 80% -120% of the opening corresponding to the current gas regulating valve, so that fine adjustment of the gas regulating valve is achieved. The opening corresponding to the current gas regulating valve refers to the opening 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; the opening degree can be sequentially reduced from 120% of the opening degree of the current gas regulating valve until the opening degree corresponding to the gas regulating valve is reduced to 80% of the opening degree of the current gas regulating valve. 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, then the opening degree is returned to the opening degree corresponding to the current gas valve, and then the opening degree is gradually reduced until the opening degree of the gas valve is reduced 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 and a maximum opening corresponding to the gas regulating valve, so as to correspondingly regulate the gas regulating valve in the maximum range. In other embodiments, the first preset range may be other ranges, for example, 90% -110% or 70% -130% of the opening corresponding to the current gas regulating valve, and the first preset range may be specifically selected according to the actual use situation, which is not specifically described herein.
In yet another embodiment, both the air intake assembly and the gas regulating valve may be adjusted when the controller confirms that the first temperature is less than a preset temperature value. For example, in one particular embodiment, the air intake assembly may be adjusted within a first predetermined range and then the gas regulating valve may be adjusted within a second predetermined range. In another embodiment, the gas regulating valve may be adjusted within a second predetermined range, and then the air intake assembly may be adjusted within a first predetermined range. In other embodiments, the air intake assembly and the gas regulating valve may also be simultaneously regulated.

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

Specifically, in the process of adjusting the air inlet assembly and/or the gas adjusting valve, the controller may sequentially obtain a plurality of second temperature values, compare whether the obtained second temperature values are greater than or equal to a preset temperature value, and continuously obtain the next second temperature value when the second temperature values are less than the preset temperature value until the second temperature values are greater than or equal to the preset temperature value, and stop adjusting the gas adjusting valve and/or the air inlet assembly. By the mode, the fuel gas can be fully combusted, and the energy efficiency of the kitchen range is improved.

By the mode, the kitchen range has high energy efficiency.
In a specific embodiment, when the air inlet assembly is adjusted, a plurality of second temperatures are sequentially obtained in the adjusting process, when the second temperatures are smaller than a preset temperature, the largest second temperature in the second temperatures is found out, and then the air inlet assembly is adjusted to a state of an air inlet speed corresponding to the largest second temperature, so that the energy efficiency of the kitchen range is improved.
In another embodiment, when the gas regulating valve is regulated, a plurality of second temperatures are obtained, when the second temperatures are smaller than the preset temperature, the largest second temperature in the obtained second temperatures is found, and then the opening degree of the gas regulating valve is regulated to a state corresponding to the largest second temperature, so that the cooker has better energy efficiency.
