Further, as shown in fig. 2, the gas sampling unit 200 includes a first pipe 210 and a second pipe 220, and the electronic olfactory detection unit 300 is disposed in the second pipe 220. Specifically, since there may be a large amount of gas produced during the cooking process of the cooker, two pipes may be provided in consideration of the processing speed of the sampled gas during the gas sampling process, one pipe, i.e., the second pipe 220, in which the electronic olfactory detection unit 300 is provided, and the exhaustion of a large amount of gas in the cooker 100 is performed through the first pipe 210, so as to achieve the acquisition of the required gas parameters through the sampling of a part of the gas, thereby reducing the workload of processing all the gases. It will be appreciated herein that the conduit design may be such that more gas flows through the first conduit 210 than through the second conduit 220.
Further, both ends of the second pipe 220 are connected to the first pipe 210, and a first valve 211 is disposed in the first pipe 210 between the second pipe 220 and both connection ends of the first pipe 210. Specifically, a valve is provided in the first pipe 210 to control the gas flowing through the first pipe 210, wherein the ratio of the flow rates is controlled by controlling the area ratio of the valve in order to secure the split ratio of the first pipe 210 and the second pipe 220.

Further, as shown in fig. 3, the second pipe 220 includes a gas input 221 near the cooker 100 and a gas output 223 far from the cooker 100, and a gas condensing part 222 disposed between the gas input 221 and the gas output 223; the electronic olfactory detection unit 300 includes a first temperature detection unit 310 and a first gas flow detection unit 320 provided in the gas input 221, and a second gas flow detection unit 330, a carbon dioxide detection unit 340, a fragrance detection unit 350, and a second temperature detection unit 360 provided in the gas output 223. Specifically, the second pipe 220 is divided according to the passage of the sampled gas, and may include a gas output end 223, a gas condensing portion 222 and a gas output end 223, the gas input end 221 is provided with a temperature measuring device for measuring the temperature of the sampled gas, so as to determine the temperature of the food according to the temperature of the gas, the gas input end 221 is provided with a first gas flow detecting unit 320 for measuring the flow of the input gas, the sampled gas is condensed into water after flowing through the gas condensing portion 222, and at this time, the gas output end 223 is provided with a second gas flow detecting unit 330 for measuring the flow of the output gas, so as to calculate the water vapor content of the gas according to the flow of the input gas and the flow of the output gas.

The condensation speed is adjusted by the monitoring results of the first temperature detecting unit 310 and the second temperature detecting unit 360. A correspondingly greater condensation rate is required when the flue gas temperature is high. The second temperature detecting unit 360 serves as a correction parameter for detecting the gas component. Because the sensitivity of the sensor is different at different temperatures, more accurate detection results can be obtained after the temperature parameters of the exhaust gas are corrected.
In the cooking process, temperature parameters of the gas in each stage in the cooking process of the food are monitored through a temperature sensor, carbon dioxide content of the gas in each stage in the cooking process of the food is monitored through a carbon dioxide sensor, fragrance value of the gas in each stage in the cooking process of the food is monitored through a fragrance sensor, and water vapor content of the gas in each stage in the cooking process of the food is obtained through a flow sensor and calculation. And (3) judging whether the cooking process of the food is normally finished or abnormal by monitoring the change of the parameters at each stage in the cooking process of the food so as to confirm whether the parameters meet the corresponding preset values. For example, in the stage of dehydrating the food material, the water content of the food material does not reach the boiling point, so that the water vapor in the corresponding gas parameters is less, and the flavor and the carbon dioxide are also less. In the stage of food dehydration, water in food materials can be quickly evaporated, the steam quantity is large, and at the moment, the corresponding gas parameters have more steam, less fragrance and increased temperature. In the caramel reaction stage, the water vapor in the corresponding gas parameters starts to decrease, the carbon dioxide gradually increases, and when the carbon dioxide increases to a preset value, the next stage is started. In the Maillard stage, the water vapor is still kept less, the carbon dioxide is relatively reduced, the fragrance value is increased, and when the fragrance value reaches a preset value, the heating can be stopped. The gas parameters corresponding to each stage may be one or more of them. It is possible to observe whether the critical gas parameters of each stage satisfy the preset conditions to determine whether each stage is completed. The operation corresponding to each stage of the cooking process of the food materials is realized by the control of the main control unit of the cooker.
