In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0027] Specifically, by detecting the sound signal generated during the cooking process through the voice control acquisition module 1, the cooking status of the food can be monitored in real time, avoiding the problem of over- or under-cooking caused by traditional timing control, and improving the cooking quality. According to the sound signal transmitted by the voice control acquisition module 1, the detection module 2 will make corresponding judgments and instructions. When the detection module 2 determines that the food has been cooked, it will send a signal to turn off the heating module 5 and stop heating; when the detection module 2 determines that the cooking process is not completed, it will continue to maintain the operation of the heating module 5 until an appropriate sound signal is detected, thereby avoiding unnecessary energy waste and improving energy utilization efficiency. Users no longer need to manually adjust the cooking time or frequently check the cooking status. The system will automatically adjust the cooking process according to the sound signal detected in real time, thereby improving ease of use and user experience.

[0028] Furthermore, during the cooking process, the heating module 5 heats the cooking cavity, and the voice control acquisition module 1 is installed at an appropriate position in the cooking cavity to detect the sound signals generated during the cooking process. These sound signals may include sounds such as food popping and boiling. The voice control acquisition module 1 converts the detected sound signals into electrical signals and transmits them to the detection module 2. The detection module 2 receives and analyzes these sound signals to determine the key nodes in the cooking process, such as whether the food has popped or been cooked.

[0029] Taking the processing of popcorn as an example, corn kernels, rice kernels and other ingredients can be placed in the cooking chamber of the cooking device. These ingredients are bound to swell and burst under the action of heating. After adding the voice control acquisition module 1, the voice control detection module 1 can detect the sound signal generated in the cooking process in the cooking chamber, and after passing through the signal amplification circuit, the sound signal is sent to the detection module 2 for detection. The detection module 2 can detect the strength and presence of the sound signal in real time, and continue to detect to determine the progress of cooking; when the voice control detection module 1 detects that there is an exploding sound of popcorn, the heating module 5 is controlled to turn on until the cooking sound stops or there is almost no sound, indicating that the popcorn has been popped, thereby reducing the problem of overheating or insufficient heating, and ensuring the quality and taste of the popcorn. The detection module 2 controls the heating module 5 to turn off according to the detection signal, so that the heating module 5 stops heating and ends the entire menu process, thereby effectively ensuring the cooking effect of the popcorn menu.

The detection module 2 controls the working state of the heating module 5 based on the analysis results. If the detection module 2 determines that cooking is completed, it sends a signal to turn off the heating module and stop heating; if the cooking process is not completed, the heating module 5 continues to work until an appropriate sound signal is detected.
