Gas cooker and control method thereof

Abstract

The invention provides a gas cooker and a control method thereof. The gas cooker comprises a burner, a fire cover, a color sensor and a reflection piece, wherein a fire hole communicated with a gas injection channel on the burner is formed in the fire cover, so that gas is sprayed from the fire hole to form a flame; the color sensor is positioned at the bottom of the burner; an avoidance channel is arranged between the color sensor and the fire hole; a reflection surface is arranged on the reflection piece and is used for reflecting the color of the flame to the color sensor by the avoidance channel so as to detect the color of the flame; the melting point of the reflection piece is higher than the temperature of the flame generated by burning of the gas. The gas cooker provided by the invention is used for detecting the color of the flame by the matching of the color sensor and the reflection piece to detect whether the flame is put out abnormally in real time, and further a user can be reminded in time when the gas leaks, so that the occurrence of potential safety hazards is avoided; the detection speed is high, the detection is precise, and the problem that the color sensor can not resist high temperature, so that the color of the flame and the leakage of the gas can not be detected by the color sensor is overcome.

Description

technical field [0001] The invention relates to the field of kitchen appliances, and more particularly, to a gas cooker and a control method thereof. Background technique [0002] Most of the existing gas cookers do not have the function of detecting abnormal conditions such as flame extinguishing due to food spillage, accidental flameout caused by working with minimum firepower, and prompting the user in time; a small number of gas cookers sense the temperature change at the burner by detecting the temperature of the burner. , to judge whether the flame is extinguished. However, this method of detecting whether the flame is extinguished based on temperature has a slow detection speed and a long response time, and cannot respond to the flame extinguishment in time and remind the user. There is no solution for the state; there are also a small number of gas stoves that detect the leaking gas after the flame is extinguished. However, this method of judging whether the flame is...

Problems solved by technology

[0002] Most of the existing gas cookers do not have the function of detecting abnormal conditions such as flame extinguishment caused by food overflow, accidental extinguishment caused by working with the minimum firepower, and timely reminding the user; a small number of gas cookers sense the temperature change at the burner by detecting the temperature of the burner , to determine whether the flame is extinguished, but this method of detecting whether the flame is extinguished based on temperature has a slow detection speed and a long response time, and cannot respond to the flame extinguishment and remind the user in time, so for abnormalities such as gas leakage within a certain period of time However, this method of judging whether the flame is extinguished based on the detection of leaked gas will cause the sensor to be inaccurate once the sensor is installed in an inappropriate position. When a gas leak is detected and the external environment affects the gas flow, the sensor will not be able to accurately detect the gas leak, which will easily lead to safety hazards
