AI Technical Summary
Technical Problem
Infrared sensors on gas stoves can be affected by the burner flame, leading to inappropriate control of the control valve due to interference with temperature measurements.
Method used
A gas stove design that includes a controller capable of determining a threshold value based on heat output information and burner/object type, adjusting the control valve accordingly to compensate for burner flame interference.
Benefits of technology
The controller effectively manages the control valve by considering the impact of burner flame and object reflectance, ensuring precise gas supply control despite interference, thereby improving temperature measurement accuracy and control valve operation.

Abstract
This gas stove provides a control valve that can properly control the temperature even when the temperature measured by the infrared sensor is affected by the burner flame. [Solution] The gas stove comprises a burner, a flame adjustment unit for adjusting the flame of the burner, a flame switching valve for controlling the supply of gas to the burner, an infrared sensor positioned in conjunction with the burner to measure the temperature of a heated object using infrared radiation, and a controller capable of communicating with the infrared sensor. The controller acquires flame information indicating the flame adjusted by the flame adjustment unit. The controller receives the temperature measured by the infrared sensor when it is transmitted from the infrared sensor. The controller determines a threshold value for determining the received temperature based on the flame information. The controller controls the flame switching valve (S87, S91) based on the relationship between the received temperature and the determined threshold value (S89, S93).
