Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to a stove fire control device and its control method. Background Technology

[0002] Currently, most traditional household gas stoves can only be manually controlled by a knob. Specifically, you press the knob to ignite the flame, and then rotate it counterclockwise to adjust the flame intensity.

[0003] With societal development and technological advancements, people's demands for quality of life are increasing, leading to a greater need for diverse cooking methods. Many people search for recipes online, but these often only provide ingredients and cooking steps, vaguely describing gas stove heat levels as "high," "low," or "medium." Since every gas stove is different, the actual heat output for each setting will vary, resulting in a mismatch between the desired and actual heat. Furthermore, users must manually adjust the heat using knobs, which can be inefficient. Since Chinese cuisine emphasizes precise heat control, these combined factors inevitably lead to poor heat management and unsatisfactory cooking results.

[0004] To address this issue, cooktops using electric control valves such as motor valves and proportional valves have been introduced to control the flame. However, these cooktops are often expensive and require a 220V AC power supply, making the replacement cost too high for users who already have traditional gas cooktops. Summary of the Invention
