Gas stove dry-burning-prevention method

Abstract

The invention relates to a gas stove dry-burning-prevention method. When a diffuse reflection photoelectric switch detects that a person exists in front of a cooking bench, a dry-burning-prevention device is not started; when the diffuse reflection photoelectric switch detects that no person exists in he cooking bench, and an infrared sensor detects that the person exists in front of the cooking bench, according to the fire magnitude, delay sound alarm is carried out, and if unmanned operation is carried out, the dry-burning-prevention device is started; when the diffuse reflection photoelectric switch detects that no person exists in the cooking bench, and the infrared sensor detects that the person does not exists in front of the cooking bench, the dry-burning-prevention device is started; after the dry-burning-prevention is started, according to a sheltered photosensitive diode, the position of a rotary knob is judged, the current fire magnitude is determined, if the current fire islarge, after it continues for T1, an alarm is given out, a motor is controlled to rotate, and the rotary knob is rotated clockwise until the rotary knob is closed; if the current fire is the medium heat, after it continues for T2, the alarm is given out, and the motor is controlled to be rotated; and if the current fire is the small fire, after it continues for T3, the alarm is given out, and themotor is controlled to rotate.

Description

technical field [0001] The invention relates to a method for preventing dry burning of a gas stove. Background technique [0002] In the 21st century, my country has initially entered the era of informationization and intelligence. With the development of science and technology, people's requirements for intelligent life are increasing day by day. In recent years, the concept of smart home has gradually penetrated into people's lives and is constantly affecting people. The kitchen is a place where people cook, and it is closely related to people's diet and life. A few years ago, Haier launched an anti-dry-burning gas stove, which uses a "patented anti-dry-burning temperature sensor" to detect the temperature of the bottom of the pot, so as to prevent dry-burning. However, improvements are still needed for the transformation of existing gas stoves and the misjudgment rate of the judgment mechanism. [0003] After searching, it is found that Chinese utility model patent CN ...

AI Technical Summary

Problems solved by technology

It can turn off the gas stove at regular intervals, but the degree of intelligence is too low, and it will be turned off during normal use, which is very inconvenient. Moreover, gear A and gear B are always in a meshing state, and there is also a large resistance to turning the knob, which makes the user experience difficult. bad question

[0005] The above several inventive devices all need to transform the existing cooker, and the user needs to replace the cooker when using
