The existing commercial frying stove mainly comprises a blower, a gas ball valve and a stove head, and the using method of the frying stove comprises the steps of firstly opening the blower and the kindling gas (the gas is required to be opened to a large extent at first), then igniting the gas by using an ignition gun, and then adjusting the size of the kindling and whether the combustion is sufficient or not according to personal experience according to the state of flame. After the kindling is normal, the size of the main fire is adjusted by adjusting the air inlet amount of the main fire and the air inlet amount of the main fire pipeline 5 so as to carry out combustion application. The current combustion mode adjusted has the following problems: 1. the tail gas emission does not reach the standard under the influence of human factors. The combustion ratio adjusted by observing the flame state by people is seriously limited to different people having different feelings, and no way is provided for ensuring the consistency of all combustion air-fuel ratios. The face-to-combustion ratio mismatch. And carbon monoxide or excess carbon dioxide is produced during the combustion process. Endanger the physical health of workers and pollute the environment. 2. Affected by factors about gas pressure. When the combustion mode depends on the ratio of air to gas adjusted manually, when the fire power is adjusted manually for application, because the actual application environment is that a plurality of gas devices share one fuel pipeline and one pressure reducing valve 8, and the gas pressure required by the state to enter the household is set to be about 2 KPa. When various gas devices are applied, the gas pressure at the back end of the house can fluctuate by about +/-0.4 KPa, and the fluctuation range is wider for some old cities or places with dense population. According to the principle that the flow rate is closely related to the pipe diameter and the pressure, the current proportion of the gas and the air is influenced. Causing air-fuel ratio imbalance for different periods of time. Further, the combustion is insufficient. 3. The service life of key components such as a mechanical gas valve is insufficient. In the application process of the commercial stove, different firepower needs to be adjusted ceaselessly to adapt to different cooking modes. The most frequent is more than 10 times per minute. The high-frequency adjusting frequency is far from meeting the requirements of the common gas ball valve. 4. The traditional frying stove has high electric power and large power consumption. Because the traditional commercial cooking range uses a common alternating current fan, the fan has low efficiency and large loss. When the air quantity is adjusted in the application process, the air quantity can be adjusted only by opening and closing the air outlet. The power consumption of the adjusting mode is fixed at the maximum value, and the energy-saving effect of increasing the electric power when the strong wind cannot be achieved and reducing the electric power when the weak wind cannot be achieved is achieved. 5. The traditional frying stove has overhigh noise in the combustion process. Because the traditional commercial stove adopts a post-mixing combustion mode, the biggest defect of the combustion mode is that gas and air cannot be fully mixed. The combustion mode without sufficient mixing generates huge detonation noise in the combustion process, and the physical health of workers is seriously influenced. 6. The conventional commercial stove is in a mechanical combustion adjusting mode, and a flame detection monitoring system is not arranged, so that when flame is extinguished in the application process, fuel gas leakage can be caused; the potential safety hazard is great. The present application can just eliminate the above problems.

In a further preferred embodiment, the controller 1 further includes a wireless communication module, the wireless communication module is electrically connected to the central processing unit, and the wireless communication module is used for performing wireless communication with an external electronic device.

The application has the advantages over the prior art that: 1. the proportional results were calculated using software programming. The combustion effect calculated by the air-fuel matching ratio is more accurate than that calculated by manual operation and human brain; the matching process is adjusted by replacing frequent manual operation, so that the possibility of misoperation is reduced. 2. The gas is admitted and is adopted and fed the zero pressure mode of regulation, avoids the influence of pressure fluctuation. The gas inlet pressure is reduced to zero pressure by using a servo principle. When in combustion, the negative pressure generated by the fan is utilized to supply air, so that the fluctuation of the gas pressure in the application process is ensured not to influence the combustion working condition at the rear end. 3. The service life is prolonged by a non-contact adjusting mode. The burning power is adjusted by a contactless Hall sensor. Because there is no contact, there is no long-time switch action like the air valve, and the phenomenon of abrasion and air leakage occurs. 4. The system adopts the variable frequency direct current fan, and is efficient and energy-saving. The advanced variable frequency regulation and closed loop feedback technology is applied to realize that when different air volumes are needed in the application process, the air volume is controlled by regulating the output power of the fan, so that the electric energy loss is regulated to be the lowest. And the rotating speed of the fan is regulated and controlled by a closed-loop feedback technology. The closed-loop control mode can effectively control the corresponding air quantity when working in different environments. 5. Noise control, this system adopts the mode work of premixing, mixes air and gas according to better proportion earlier, becomes the gas that the intensive mixing is good, and then sends to the furnace end and burns, because the gas has already been mixed before the burning. Therefore, the combustion process is stable and smooth. The noise is very effectively reduced. 6. And the ion type flame detection is adopted, so that flameout gas leakage is prevented, and the application safety is ensured. The system adopts ion type flame detection, and designs a long-time open fire for making fire seeds. The fire type and main fire all have gas solenoid valve, when the system detects the fire type and extinguishes, can make in 3 seconds and close the gas action, prevent that the gas from leaking.

The invention also provides a control method of the cooking range system, which comprises the following steps:

s2: the controller 1 controls the high-pressure ignition mechanism 11 to start;

s3: opening the first electronic valve 3, and starting combustion of the fire seeds;

s4: opening the second electronic valve 4 and the premixing fan 7, and starting combustion of the main fire;

s5, closing the second electronic valve 4 and the premixing fan 7, extinguishing the main fire, and continuing to burn the fire species;

s6: the range system is turned off, the first electronic valve 3 is closed, and the main fire and the fire are extinguished.

During the starting time of the stove system, the fire seeds are always in a burning state, the flame of the fire seeds is very small, and the effect of igniting the main fire is only achieved. Because the commercial frying furnace has too frequent ignition and flameout frequencies in the use process, the method adopts a mode of reserving fire seeds, reduces frequent use of a high-pressure ignition mechanism for ignition, prolongs the service life of the high-pressure ignition mechanism, and can ignite the main fire by directly opening the gas of the main fire pipeline without igniting every time when in use, thereby being more convenient to use.

In a preferred embodiment, after the stove system is started, the premixing fan 7 is started to clean the residual gas in the main fire pipeline 5, and then the step S2 is performed to remove the residual gas in the pipeline, so as to ensure safety.

When the power of the stove system is adjusted, the rotation speed of the premixing fan 7 and the flow rate of the second electronic valve 4 are simultaneously changed. The air flow and the gas flow are always in proper proportion, and the gas is more fully combusted.

In the preferred embodiment, when the flame detection mechanism 12 does not detect flame, the first electronic valve 3 is automatically closed, and the alarm mechanism gives an alarm and stops; when the fire is ignited, if the fire is not ignited for many times, the alarm mechanism gives an alarm and stops the machine.

The stove system controller 1, the stove control system and the control method of the invention control whether the main fire pipeline 5 and the kindling pipeline 6 are ventilated or not by two electronic valves, when the commercial stove is used, the kindling pipeline 6 is burnt, when dishes are needed, the main fire pipeline 5 can be communicated for use, repeated ignition is not needed, and the stove is very convenient.

Referring to fig. 2, the working process of the furnace system is as follows: after starting, firstly purging the main fire pipeline and the kindling pipeline to remove residual gas used last time; opening the igniter and the first electronic valve; if the gas burner is ignited, the second electronic valve is opened, the air and the gas are mixed according to a set proportion, the mixed air enters the burner through the main fire pipeline for combustion, if the flame detection system detects that the flame is not combusted, the gas burner is automatically stopped, and the first electronic valve and the second electronic valve are closed.
