It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
An embodiment of the gas cooker of the invention is shown in fig. 1. In fig. 1, the present embodiment includes:

The temperature change is positively correlated to the volume of the vessel and the medium. The volume of the cooker is closely related to the cooking process and can be input through an interactive interface or obtained through a measuring and sensing mode. And forming heat source fire data of the container with the determined volume in a range required by the temperature requirement according to the step data and the cooker volume data, forming required real-time gas flow data according to the heat source fire data, and forming cooking process fire target data by utilizing the time-series real-time gas flow data.

Those skilled in the art will appreciate that the gas cooker drives the throttle valve or the air door to adjust the mixing ratio of the gas and the air through the control knob, so as to adjust the combustion intensity (fire) of the gas. The heat output efficiency and the adjustment degree of the control knob adjusting mode can be determined according to the specific gas stove model. The control knob shaft can be controlled to a specific degree by sensing the rotation angle of the control knob shaft, and the firepower can be changed and can be visible in the state of the control knob by influencing the rotation angle of the control knob shaft.

The gas cooker of the embodiment of the invention forms a flexible and reliable cooking system around the existing gas cooker. The cooking strategy forming device introduces rich cooking schemes to form a complete cooking control process, and the modification of the existing cooking schemes is utilized to meet the customization of cooking requirements. The main fire target parameters of the cooking process are determined by creating a thermal timing requirement for the cooking process through the customization step and the quantification of the cookware volume. Furthermore, the continuous control process of the gas cooker is formed by matching the firepower target parameters with the existing mechanical control process of the gas cooker, and the correction fusion of the human-in control and the automatic control is realized in the continuous control process, so that the firepower output of the gas cooker in the cooking process can be independently finished and manually adjusted, and the good balance of the gas utilization efficiency and the cooking quality is realized.

Since the distance acquisition process can be controlled at or before the start of the heating process, thermal infrared signal interference can be avoided.
The gas cooker provided by the embodiment of the invention directly acquires the contour data and the diameter data of the cooker by using the distance sensor to form the volume information, and can aim at the cooker size with lower specification. The setting position of the contour distance sensor is provided with a determined coordinate, the acquisition distance determines the length of the reflecting point, the probe angle determines the azimuth, and the three are combined to form the space coordinate of the reflecting point and the plane coordinate expression of the reflecting point.

Step 170: a set of key-value pairs for the programmed cooking regime is established by correctly mapping the contacts.
A quantized description of the determined programmed cooking regime is formed by vector data synthesis of key value pairs.
The feature key value pair is [ cooking recipe name: eigenvector values ]. The feature vector values are two-dimensional arrays, with each array element characterizing a quantized vector value of a specific (or implicit) feature of the cooking recipe.

The outer side of the stove frame is far away from other fire trays.
Step 212: contour distance sensors are arranged on the arc track at equal intervals, probes of the contour distance sensors are directed to the circle center of the arc track in the radial direction in the horizontal plane, and the pointing angles of the probes of the contour distance sensors in the vertical plane are sequentially reduced.
The pointing angle may be determined based on the radius length of the circular arc track, for example, the pointing angle (included angle with the horizontal plane) starts 70 degrees and decreases by 3 to 5 degrees.
Step 213: on the outside of the hob or on the opposite side of the fire control knob 44 with reference to the fire pan 40, diameter distance sensors are provided equidistant along the radius of the circular arc trajectory, the probes of which are directed towards the vertical gas burner panel, facing upwards.
As will be appreciated by those skilled in the art, the profile distance sensor and the diameter distance sensor are preferably of the millimeter-scale precision type, and the sensor type is preferably of the infrared band optical signal type.
Volume estimation process:
step 214: judging whether the acquisition distance of the contour distance sensor exceeds the radial distance of the arc track, if so, discarding the acquisition distance, and if so, discarding the acquisition distance.
The acquisition distance exceeding the radial distance indicates that no container is present in the defined space above the fire tray. An acquisition distance exceeding the height threshold indicates that the container diameter has not been reached.
Step 215: and determining the spatial coordinates of the profile reflection points in the three-dimensional coordinate space according to the setting positions of the profile distance sensors and the probe orientations.

According to the comparison of the corresponding acquisition distances of at least three adjacent profile reflection points, the jump can judge whether the profile curve of the container has abrupt change, which means whether the profile of the container has larger change at the corresponding height. The position of the change in the profile of the container can be determined by continuous comparison.
Step 218: the local radius of the container is determined from the height data of the diameter distance sensor.
When the effective height data is consistent, the vessel is described as being primarily cylindrical.
Step 219: cooker volume data is formed from the height data and the vessel partial quantization profile data.
